Through Hole Resistors

Through hole resistors are resistors which can be installed directly through the printed circuit board (PCB). These resistors are generally made from resistive materials such as carbon film, metal film, metal oxide, and wirewound materials. In some applications, through hole resistors are preferable and advantageous because they can provide higher power dissipation ratings, better frequency response, better heat dissipation, and better environmental protection, compared with surface mount resistors.

RNC55H9311BSB14

RNC55H9311BSB14 is a through hole resistor from Vishay which can be used in a wide range of applications requiring increased performance. It is a thick film resistor with power rating of 5W and has a robust design. The resistor element has a size of 5536 (14.17mm x 11.3mm x 5.5mm) and it is suitable for direct through hole mounting on the PCB. The resistor element features an alumina substrate for improved heat dissipation. The resistor is rated for up to 10V and has a tolerance of ±10%.

Application Field of RNC55H9311BSB14

RNC55H9311BSB14 is suitable for a wide range of applications requiring high stability and repeatability. These applications include power supplies, motor drives, servos, telecommunication systems, and industrial control systems. Additionally, this resistor is ideal for applications where the environment may be hostile due to high temperatures and/or humidity. This is due to its robust design and improved heat dissipation capability.

Working Principle of RNC55H9311BSB14

RNC55H9311BSB14 is an leakage proof thick film resistor which works on a simple yet effective principle. A thin film of resistive material is applied onto an alumina substrate, which has a large surface area to dissipate heat away from the resistor. The resistive material is then etched to form the resistor element which has an extremely low vapour pressure and is composed of noble gases in order to increase the stability of the resistor’s electrical parameters. Once the termination has been made, the resistor element is sealed in order to protect it from hostile environment conditions. This results in a high power rating and a low temperature coefficient for the resistor.

Conclusion

Through hole resistors have a wide range of applications due to their increased power dissipation, better frequency response, better heat dissipation, and better environmental protection than surface mount resistors. Among these through hole resistors, RNC55H9311BSB14 is a thick film resistor with a size of 5536 (14.17mm x 11.3mm x 5.5mm) and a power rating of 5W with a tolerance of ±10%. This resistor is ideal for applications requiring high stability and repeatability, such as power supplies, motor drives, servos, telecommunication systems and industrial control systems, due to its robust design and improved heat dissipation capability. The working principle of this resistor involves the application of a thin film of resistive material onto an alumina substrate followed by etching to form the resistor element. This is then sealed in order to protect from hostile environments.
